As Long Island cops continue their investigation of millionaire Ted Ammon’s murder, The Post has learned that his wife’s personal assistant filed a bizarre police report last year saying someone had broken into his apartment and tried to make him look like a drug addict.

Steven Guderian, of 36 West 86th St. in Manhattan – Generosa Ammon’s assistant – told police that a burglar placed hypodermic needles on his bedside table. He claimed the incident was an attempt to incriminate or intimidate him.

Asked if he had any idea who might have committed the crime, he told cops he was having problems with Ted Ammon, sources said.

Ammon knew of the reported break-in.

Some six months before his murder in East Hampton, he told a friend that Guderian had faxed him a note in which he said the alleged crime was being investigated by NYPD officer James Pelosi – the brother of Generosa’s new husband, Danny Pelosi, a possible suspect in the murder.

James Pelosi was and is currently assigned to a precinct in Queens. He told The Post yesterday he knew nothing of the crime report.

“That’s news to me. I don’t like my name being thrown around like that,” Officer Pelosi said, when told of the note to Ammon. “That would be referred to the precinct that covers that area.”

Officer Pelosi added he did not know that Danny, who was arrested for drunk driving in 1998, told cops his name was James Pelosi – until fingerprints proved him a liar.

Yesterday, Guderian declined to comment on the reported break-in or the fax to Ammon.

Suffolk homicide investigators are still poring over Danny Pelosi’s cell-phone records to determine if his calls were relayed from cell towers near the scene of the murder last October, in an effort to place him in the vicinity.
